Answer 1

Is the answer c or d i say c

Answer 2

Answer:

C. 14,645 students

Step-by-step explanation:

Let x be the number of students who think tuition is too high if there are over 25,000 students at the university,

So, the ratio of students who think tuition is too high and total student = $\frac{x}{25000}$

Given,

Out of 3421 students, 2004 think tuition is too high,

Thus, the ratio of students who think tuition is too high and total student = $\frac{2004}{3421}$

$\implies \frac{x}{25000}=\frac{2004}{3421}$

By cross multiplication,

$3421x=2004\times 25000$

$x=\frac{50100000}{3421}=14644.8406899\approx 14645$

Hence, the predicted number of students who think tuition is too high is 14,645.

Option 'C' is correct.
